In recent years, local tourism has been gaining traction as one of the measures for regional revitalization in Japan. One of the organizations that support these are the sightseeing volunteer guide organizations. These organizations have various kinds of information that are helpful for local tourism and active information transmission is desirable. On the other hand, many organizations face the issue of the information transmission as their aging volunteer guides find it difficult to handle information devices. This study therefore aims to provide support for continuous information transmission by local sightseeing volunteer guides via social media, and attempts to clarify the transmission of sightseeing information that matches the characteristics of social media through proof-of-concept demonstrations with the Historical “CULTURAL PATH” Guide Volunteers in Nagoya City.
